The magnetic structure of the heavy-fermion antiferromagnet Ce2RhIn8 is determined using neutron diffraction. It is a collinear antiferromagnet with a magnetic wave vector (1/2,1/2,0) and a staggered moment of 0.55(6)\ensuremathμB per Ce at 1.6 K, tilted 38(2)\ifmmode^∘\else\textdegree\fi from the tetragonal c axis. In spite of its layered crystal structure, the phases for the magnetic moments are the same as those in the cubic parent antiferromagnet CeIn3. This suggests that the cubic CeIn3 building blocks have a stronger influence on magnetic correlations than intervening RhIn2 layers, which give the material its apparent two-dimensional lattice structure and renders CeRhIn5 an incommensurate antiferromagnet.
